Prototype for the personification of Alexandria?

I don’t mean to suggest a direct prototype, just the sort of possible inspiration for the design of RRC 419/2. The above gem is described as “Head of Tyche (Cleopatra I?) Wearing the crown and four loops of isis, profile to the left.Behind the back of the neck, emerge a bow and a quiver.” Maybe. Why the bow and quiver? Some Artemis connection?

Notice the coin below that a Hellenistic royal diadem is interlaced with the turreted crown. I’ll need to think about what that might mean more…
